Patented cc. 1931 BRUNO FASSZHANN, OF Emma", Gr a ASSIG-NOR T ADDRESSOGBAPE (30., OF CEIGA, V ILIJHQ'QIfi smart FETNG DEVECE The invention relates-to an address'printing machine having a sheet feeding and registering device and an object is to mount the sheet feeding and registering device so as to be adjustable on the frame work of the address printing machine transversely of the path of the paper. I

Another object is to provide a sheet feeding and re 'stering device that will be adjustahle re ative to the path' of the paper movement without altering the feeding arrangements thereof and which may be clamped in various adjusted postions.

A constructional example of the invention 35 is illustrated in the accompanying drawings in which:

Fig. 1 is a lateral elevation viewed from the direction of the paper feed.

; Fig. 2 is a partial lateral view.

Fig. 3 is a partial section on the line A--B in plan view and i Fig. 4 illustrates on a larger scale a lateral view of the driving wheel which is axially displaceable onthe driving shaft.

1 is the table of an address rinting machine, 2 the magazine for the printing plates from which the latter are conveyed intermittently as known to the printing position and after an impression is made by a platen 4, ar-' ranged on an oscillable printing arm 3, are delivered to a convenient collecting trough.

The movement of the printing arm 3 as well as, that of the plateconveyor device is ef-- fected by a crank 5 which together with the movable friction jaw 6 is arranged on aboss. By means of a treadle and a sprin not shown the friction j aw 6 may be forced om the inside against the rim of a wheel 7 whereby the crank 5 is coupled with the latter. The wheel 7 is driven by a belt 8 from an elect'romotor and an interposed pulley 9. The wheel 7 is rotatably journaled on a stationary axis 10 and the boss 11, arranged on which is the crank 5, and the movable friction jaw 6 are rotatable on the hub 12 of the driving wheel 7 all of which partsmay be assumed to be known.

13 and 14 represent the lateral walls of the sheet feed device journaled in which are the 50 shafts 15, 16 for the discs carrying the tapes 17, 17', 17" and the feeding rollers for the sheets as well as the driving wheels and shafts. Arranged on the walls 13 and 14 is a stacker table 18 adapted to be raised or lowered by means of a toothed rack 19 and pinion 20. Mounted on the shaft carrying the pinion 20 is a ratchet wheel 21 and co-operat ing with the ratchet is apawl adapted in known manner to raise the stacker table 18 in dependency on the height of the pile 22. Situated on the outside of the wall 14 is an air pump 23 for the generation of the requisite suction or pressure for the sheet lifting and separating device (not shown). The pump oscillates about a stationary pin 24 on wall 14 while the piston is moved up and down by a crank 25. The crank 25 is secured on a shaft 26 driven by a toothed gear wheel 27. This shaft is by preference used for effecting all controlling operations of the sheet to registering mechanism; for example, the up and down motion of the feed roll operating shaft 28 of the sheet lifting device and so on. The feed rollers 29 co-operate with a roller 30' which is driven in the same direction as the shaft 15 for the tapes and together with it .by the intermediate gear wheel 31. The latter meshes with a gear 32 journaled in the wall 14 (Fig. 3) and axially movable on the driving shaft 33. The rotary movement of so shaft 33 is transmitted by longitudinal grooves 34 in the shaft 33 through the keys 35 (Fig. 4) to the gear 32. Bevel gear wheels 36 and a spindle 37, journaled'within the hollow axis 10. The driving shaft 33 is connected with thereleasable boss 11 by end claws 38 on a disc 39, which is rigidly connected to the spindle 37, the end claws being permanently seated in corresponding notches in the boss 11.

The feed of the sheets takes place in known manner as follows: y

The uppermost sheet of the pile 22 is raised by a suction member and brought between the rollers 30 and 29. By these rollers the sheet is fed on to the running tapes 17 which convey it between adjustable guide lays (not shown) to the printing position 45; With the aid of controlled retaining devices the sheet is held in position during the impression. After the impression is made it is released and conve ed by the tapes 17 to the delivery point. he latter is situated at the side of the machine frame opposite to that of the feed device. The rollers about which the feed tapes are directed at this end of the bed are clisplaceably arranged to be adjustable transversely to the ath of the sheets across the machine. To t is end the lateral walls 13, 14 of, the feed device are provided with appropriate clampin means such as clips 41, 42 adapted to be displaced and fixed along parallel tubular members 43, 44. By preference the parallel guide tubes 43, 44 are made to form part of the frame of the address printing machine.

By loosening the clips 41 and 42 the entire sheet feeding device may be shifted transversely of the path of the sheets across the machine. When the feed device is moved transversely, the gear 32 slides along the shaft 33 and consequently the driving arrangements are in no way altered. When the feed device is so shifted transversely the rollers at the end of the bed opposite the feed device and about which the feed tapes are directed are correspondingly shifted so that the sheets will move in a straight line across the bed of the machine and furthermore by so shifting these rollers the tape is prevented from running off.

In the fore oin description I have set forth a selecte embodiment of my invention but it is to be understood that this is susceptible to variation and modification without departing from the spirit and scope of the following claims.

I claim 1. In a sheet feeding device, a member supporting a pile of sheets, means for moving said supporting member whereby the uppermost sheet will be maintained in withdraw ing position, means for withdrawing the sheets from the ile, feeding tapes, means for operating said eeding tapes, feed rollers for feeding a withdrawn sheet to said feeding tapes, means for operatin said supporting member moving means, s eet withdrawing means and feed tape operating means, a driving means, and means connecting the operatmg means to the driving means whereby said operating means may be moved relative to said driving means without interrupting the driving connection therebetween.

2. In a sheet feeding device adapted for use with an addressing machine or the like and embodying a frame, means connecting the frame of the sheet feeding device to the addressing machine for adjustment transvrsely of the bed of the addressing machine, operating means in said sheet feeding device, a driving means supported by the frame of the addressing machine, and means for slidably connecting the operating means to the driving means.

3. In a sheet feeding device adapted for use with an addressin machine or the like, means connecting the sv eet feeding device to the addressing machine for ad'ustment transversely of the bed of the mac ine, operating means in said sheet feeding-means, a drivin means supported by the frame of the lu dressing'machine, and means connecting the operating means to the driving means whereby said sheet feedin device may be adjusted transversely of said (1 without altering the connection between the operating means and the driving means.

4. In a sheet feeding device adapted for use with an addressing machine or the like, means connecting the sheet feeding device to the addressing machine for adjustment transversely of the bed of the machine, an operating gear journaled in said sheet feedin device, and a driving means including a shaft slidably and rotatably connected to said operating gear whereby said sheet feeding device may be adjusted transversely of the bed of the machine without alteringthe driving connection between said driving means and said operating means.

In testimony whereof I afiix my signature.
